My url's look like this //classifieds/search/region,something/

I want it to rewrite to //classifieds/state/something/

note: If i look at the url in the browser the words after "classifieds" are greyed.

my .htacces has this:

<IfModule mod_rewrite.c>
    RewriteEngine On    
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
</IfModule>
